Beit known that I, ARTHUR R. HAVENER,

a. citizenof the United States, residing at Wayland, inthe county ofMiddlesex and State of Massachusetts, have invented new and usefulImprovements in Feeding Mechanisms for Rivet and Cap Setting Machines,of whichthe following is a specification.

This invention relates to machines for feeding disk-shaped'articles suchas the caps for rivets.

The object of the invention is to provide a rivet-cap feeding mechanismwhich is simpleand eflicient in action. j

The application is a division from the'app'lication of Arthur R.Havener, rivet and cap setting machine, Serial No. 220,193, filedMarch4, 1918. c

.The' invention consists in a cap feeding mechanism hereinafterdescribed in the specification and particularly pointed out in theclaims. j "Referring to'thedrawingsgr V Figure 1 is a; left hand sideelevation of a rivet cap setting machine with my 'improved cap feedinginstrumentalities embodied, therein. 1

Fig. 2" is a longitudinal central section of said machine.

"Fig. 3 is a detail plan view of the rivet:

cap feeding instrumentalities. igs. 4.- and 5 are detail .plan views'simllar to Fig.v 3 illustrating the cap feeding in strumentalities indifferentpositions. a

Like numerals refer to like' parts' throughout the several views of thedraWingS. In the drawings, 6 is the frame'of the machine, 7 is theanvil, 'Sthe work-support, 9

the rivet driver and 10 the rivet carrier.

11 and 12 are the horizontal and- "inclined portions, respectively, of araceway 'l3 which feeds the rivet caps from a rivet cap hopper 14 tothe'anvil 7.

'The' rivet caps are deposited in mass in' the hopper 14 and are fedfrom said hopper down the inclined portion 12 of the raceway 13 untilthelowermost rivet'cap115 on said inclined portion 12 of the raceway restsagainst the upper edge of a slide as illustratedin Fig.3.

Arivet cap detent and feed finger 17 consists of an arm 18 which ispivoted at '19 to V the'frame of the-machine and terminate in as saidslide is'moving anvinclined portion 20' at its forward end,said-inclinedportion'20 being adapted to be engaged'by the front edge ofthe slide 16 forward in a manner hereinafter described; A plate21 isfastened to the arm 18 and said plate hasalateral wedge-shaped proection22 thereon which is adapted to enter between'the lowermost rivet cap 15on the against' movement downwardly on the 'inclined portion of theraceway by the projection 22 on the plate 21.

oflto a pin 25 and at the other'end thereof to apin 26 bearing againstthe frame of the machine. Said pin 25 is fast to the arm 18 andconstitutes a stop pin to limit the dis-- tanceto which the arm 18; canbe 'moved by the spring 24, and when the parts are in the relativepositions illustrated in-Fig. 3

side of the slide 16.

the free end of the arm 18v rests against-the 'The raceway 13,consisting of the inclined portion 12 and the "horizontal pOrtionll, is

. A spring 24 is connected at one end there formedby two parallellydisposed members 27 a'nd 28 whichhave a space 29 therebetween. Thesemembers 27 and 28 are each grooved at 30 and 31, respectively, upontheir inner adjacent faces to receive the opposite sides' of the rivetcaps as they are fed along the raceway. The raceway 13 terminatesat'jlits front end in two. fingers 32 and 33 pivoted zit-34c and 35,respectively, to

.the frame of the machine'and terminating'at their 5 front =ends' insegmental circularshaped recesses 36 and 37 into which" the rivet cap isfed when in its forward position by the slide-.16. j 'Thes'work-support8 has aproject'ion 38 thereon-constituting a stop against which thefinge'rs 32 and 33 abut-when in the position illustrated-in Fig. 3. Saidfingers and 40,-. respectively.

[are moved tow'ard each other by springs 39 reciprocatory motion isimparted to the slide 16 by a bell-crank lever 41 which is pivoted at-12 to the frame of the machine and the vertical arm 1?) ofwhich-engages anear d4: on the slide 16. The horizontal arm" of saidbell-crank lever has a circular sha 36d end 15 which enters a slot 16 ina mein er 17. The member 47 constitutes a link, the upper end of whichis connected by a pin 18 to a lever 49 and the lower end of which ismounted. upon a crank 50 formed on a shaft 51 journaled to rotate in theframe of the machine.

A rotary motion. is imparted tothe shaft 51 by a clutch 52 which isdrivenfrom the main driving shaft of the machine. The ear 4A is heldagainstihe vertical arm 43 of the bell-crank lever 41 by a spring 54;

connected to the vertical arm i3 of the bellcrank lever 41 at one endthereof and at its opposite end 18 connected to anarm 55 wvhich isfastened tothe slide 16, so that the slide16=is carried forward by thespring 54: V

V motion imparted theretoby arlever 57- pivotedat 58 to the frame' ofthe machine and having a rocking movement imparted thereto bytheinclined lower edge 59 of the slide 16 which, in. its forward. .andbackward movement, engages airoll .60 journaled on the rear end of thelever ,57.

The general operationof the cap. feeding mechanism hereinbeforedescribed is as fol lows: Assumingthe shaft 51 to be. rotating in thedirection of ithe arrow. a, Fig. 2, the bellcrank levers]. *willbe-operated-to move the slide 16 rearwardly until thefront end of saidslide disengages the free endof thearm'18 (see-Fig.3) and said arm willthen be moved bythespring 24 to the position ill'ustratedin 'Fig. 4,withthewedga shaped projection22 projecting between and pressing againstthe lowermost-rivet cap 15 on the inclined portion 12 ofthe raceway 18and against the next to-the lowermost rivet cap.'23'on saidracew-ay. Thelower edge'of thelon' ermost rivet cap is now bearing against the upperedge of the slide 16.

Upon a further movementof'saidslideto ward the rear the upper edgeofsaid slide will become disengaged from the -rivet cap 15 and thespring 2 1 will then cause the arm18 tospring forwardly into thepositionillustrated in Fig." 5 andthns drive the rivet cap 15 forward onto andalong thehorizontal portion 11 of therivetcap raceway,

while at the same time the projection 22 holds the rivet cap 23 and thecolumn of rivet capsabove the same against movement onthe rivet capraceway. 7

During this rearward movement of the slide 16 the incline 59"o1rthelower edge of said slide engages the roll 60 and rocks the lever 57 toraise the anvil 7 and at thesame time the lever 49. is: rockedto movethe driver 9 downwardly and the rivet is set in the rivet cap in amanner'well known to those skilled in the art, but forming no part ofthis invention.

During the settingiofthe rivet in the rivet cap the anvil 7, during itsupward and carries the rivet vcap, which at that time is held betweensaid'fingers in the segmental recesses 36 and 37, upwardly and againstthe lower surface of the material to which the rivet and rivet cap:areto beattached.

After the rivet has been set the motions of the different partshereinbefore.described will be reversech .that is, the rivet carrier andrivet driver. will be moved. upwardly, the anvil will move downwardl gthe fingers 32. and 33will. be brought toward each other by their.respective springs until .they; engage" the stop; 38, .and thebellecrank lever 41 will be rocked to allow thesli'de 16 to be movedforward. by the spring 5 1 until j the front. end ofsaid slide 16engages the i11- clined end 20015 the arm18 and pushessaid arm out oftheraceway slot, whereupon the projection 22 willnbe removed from engagement with..therivet cap 23 and said rivet .cap will then .sli'de.downtheinclined portion of the :.r.ivet cap raceway until its lower edgeengages the upper edgexof the. slide 16. Meantime-the rivet-zcap ll'iwhich has been forced onto and along theihorizontal portion 11 of theraceway l 'will be engaged by the front end of the slidelG and fed for-WELFClZlJGtWGGlLthG: fingers 32Tand 33 .until it lodges in thesegmental. circular recesses 36 and 87 on the frontend of saidjfingersanvil and therivet carrier 10. The slide 16 will then .be moved (back tothe position. illustratedin. Fig. .2' and the operator will '80movement, forces the vfingers82 and 33 apart.
